Be it known that I, J us'rus R. KI'NNEY, a-

which the fbllowing is 'a specification.

This invention relates to apparatus for applying liquids to roads, and has for its b hot gases and then applied to the road either in the form of a spray or in larger quantities, as may be desired, and which may be utilized also in flushing the roads,

flushing heads being attached in lieu of the 7 oil; Sprayers.

Another object of the invention is to pr0- vide an oil heating device which. will be under the instant control of the operator at all times whereby the material may be heated to any desired degree of temperature as required even while on the way to the place of operation, thus avoiding vexntious delays.

A further object of the invention is the provision of means for agitating the mate? rial in the tank to insure awuniform tern? peruture throughout the entire loud.

' The invention consists in a'selflpropelled vehicle, the. engine of which is a d-opted to drive arotury pump either while said vehiole is moving or-at a. standstill, said pump being adapted for use in filling the tank or emptying it either through a discharge pipe .or through spray "nozzlesf;

The invention further-cons sts in certain novel features of construction and arrangement of parts which will befnlly understood by reference to the description of the drewings and to the claims hereinafter given.

blmilar characters designate arts throughout the several figures of ftheI raw-g in s. I '1 n the drawings, 10 is a tank provided at the top with the filling dome 11 throng 'WhlCll the tank may be filled from a'ny sui able source of supply located above 'sa'l tank. The tank 10 is supported on cradles; y 12 infide'ofxflutm'etal bersbent to new seat for the tank witlr'inwnrdl extending slemountabl' feet which. are secured tote frame i Straps 14 ass ground the t a.nk-10..a.nd

re demountable frame .13 is supported on -the chassis or "frame. 15'' of a truck ha vingthe' supporting wheels16 16* and anengine 17 mounted thereon 'by which. the rear wheels 16 may be driven in any we'll-known- Inn-n ner through the medium of'the driving shaft 18, the transmission 'meohanism 19,

ment is imparted by means of and the transversely disposed revoluble shafts 20.

believed is suflicient for an understanding of the means employed for driving the truck. The engine driving-shaft 18 is mounted in a tubular member 24 in which it is freely revoluble and said tubular member 24 is provided with the open 'couplin 25.

Within the coupling 25 the s aft 18 has keyed or otherwise secured thereto a sprocket wheel'26 from which rotary movean endless chain .27 to a sprocket wheel 28 loosely mounted on the revoluble shaft 29 of a rotar pump 30.

he sprocket wheel 28 is prevented from moving endwise of the shaft 29 and has keyed or otherwise securedto its rear end one part 31 of a clutch, the other coacting part 32 thereof being keyed to and slidable lengthwise of the' shaft 29 as indicated in Fig. 10 of the drawings.

The member 32 has an annular peripheral groove therein into which projects the studs of a forked member 33 secured to a slidin rod 34 mounted in bearings 35 and connected at one end by a pivot 37 to an arm 38 se cured to a vertical oscillating shaft 38, the upper end of which hassecured thereto an arm 39 the outer end of which is connected to one end of a link 40, the opposite end of which is articulated tov the operatin lever 41 located conveniently to the Chen eurso that he may throw the clutch members 31-32 into and from engagement at will.

By means of this construction the pump 30 may be operatedby the engine 17 when the vehicle is moving over.the 'road ."or it may be.thrown out of commission as de nism is thrown out of. commission in the usual manner, the ump 30 maybe placed 1n commission at W111 and be drlven by said en me.

he inlet side of the pump 30 connected means of'a pipe 42 to a suction stralner 43 of any well-known construction, and a discharge strainer 44 of any desired type is connected to the discharge outlet of said. pumpby meanso'f'the pipe 45, having a 3- way valve 45 i, t'h.erein.-

The pipes-42-45 are connected by a bypass ipe 46 having .a relief valve 47 theredischarge of material therethrough.

The pipe 48 is connected to the member 53 secured to the bottom of the tank 10 by a discharge pipe 54, said member 53 hav ing a valve seat 55 with which coacts a closing valve 56 shown in Figs. 3, 12, and 13 of the 'drawings- Y The valve 56is mounted upon the lower end of a tubular valve stem 57 extending upwardl through the tank 10. The lower end of t e' stem 57 has a hearing at 58 and revolubly mounted on its up er end is a revoluble'sleeve 59preventec roin end'wise movement thereon.

The sleeve is threaded to a fixed nut 60 in the upper side of the tank 10 and maybe rotated therein by the handle 61 to move the valve 56 to and from its seat 55 to regwhich the material sired. It is obvious, moreover, that when the vehicle is at rest. and the engine 17 ,is'

.mally'closed by in operation, while the transmission mocha-,

end of which is secured ulatc the discharge of material from said tank.

The tubular'stem 57 extends through the hub of the handle 61 and has at its upper end a pet cock 62 adapted to close the passage through said stem 57 when the valve 56 is open. When the valve 56 is closed the pet cock is moved into the position shown in F ig 13,' thereby permitting the air to discliar e pipe 54.

On either side of and parallel to the stem 57 are distance rods 63 extending across the tank 10 and serving to strengthen-the same.

The pipe 46 also has leading therefrom a discharge pi .e 64 having a cutoff valve 65 therein. he end of the pipe 64 is threaded to receive a hose through which the contents of the tank may be discharged when it is desired to empty the tank without sending the material through the sprinkler systems. From the bottom of the strainer pass through the stem 57 into the i 44 is, another discharge nozzle 66 through may be drained from the strainer. The discharge nozzle is northe valve 67. The pipes 51 are provided with T-unions 68, the downwardly extending branch of each of which is provided with a pipe 69. end of each pipe 69 has mountedthereon an oscillating member 70 from which extends the horizontal pipe 71 which is adapted to be oscillated through an! arc of a circle.

The lower To the front end of each pipe 71 is se- J cured a depending pipe72' to the lower 73 having an upwardly The pipes 72 are connected by the distance the oil spray pipe extending rib 74.

rod 75 by which the pipes 71 will be prevented from oscillating independently of each other. Pins 76 extending upwardly from eadh pipe 73 on opposite sides of the rod 7 5 letain the pipes 7 3 in alinement duringrthe oscillating movement of the Cpipes 71.

.he oil spray pipes 73 are provi ed with the usual spray nozzles 77. Each ipe 71 has secured thereto one end of a cor 7 8 the opposite end of which is coiled about an inclined shaft 79 having a bearing at 80 on the rear transom 81 of the frame 13 and pro vided-with an operating handle 82 at its outereni l. The operator on his seat 83 may turn the shaft 79 to move .the oil spray pipes 7 3 transversely of the tank 10. I

In each pipe 51- 1s a valve '84 which is adapted ,to control the passage of niatenal through; said pipe. Each valve 84 is rovided with an operating arm 85 connecte by a link 86 to an arm 87 secured to the oscillating shaft 88 or 89 towhich-oscillatory movement is imxigrted by means of the foot lever 90 or 91. ach of the shafts 88 or 89 has loosely mounted thereon a lever'92 con-- nected by a link 93 to an arm 94 one. vert cal oscillating shaft 95, the lower end of which has secured thereto an arm .96 connected by alink 97 to an annular member 98 sin-roundingthe periphery of a sprinkler head 99. The sprinkler head 99 is provided with peripheral perforations 100 in its under side which are adapted to be, closed by the movement of the member 98 about the axis of said head. The head 99 is located on which communicates with one ranch of the T-union 6S ad'acent to which is a valve 102 by which the ow of material to the head 99 may be shut ofi when the oil spray pipes7 3 are in use. Between the oil spray pipes 73 and the member 70 the pipe 715 is provided with a three -wa valve 103 operable by hand to cut off the cischarge through said pipe entirely or confinin it to discharge through the oil spray pipes 3 or through the flushing heads 104: which are mounted on the side branch of said valve 103 and may be adjusted with the delivery slot at any desired 1 angle.

7 1 the projecting lug.107, said tracks'being coni which axis the pipe 71 may be moved, carry Supported from the frame 18 by the/rods 105 are the curved tracks 106 onwhich rests centric with the axis of-the pipe 69 about ing with it the oil spray ipe 73 and the flushing head 104. The s afts 88 and 90 may be oscillated by the foot levers 90 and 91 or they gnay be oscillated by the hand le vers 108 and 109 respectively."

The tank 10 is provided at its front end with a chamber 110 from which extend to and throu h a head 111 near the rear thereof a plum ity of heating pipes 112 throu h Wl'L'LfIll'hOtlLll is adapted to pass fromt e heater chamber 113 situated at the rear end at therein. i

The casing 43 has secured to its outer wall a valv 121 through which the tank 10 is adapted to be filled with liquid, the valves 56 and 65 at this time being closed and the liquid passing through the strainer 43 and pipe 42 to the pump 30, from which it is forced through the pipe 45 to a valve 122 which is open, and then throughthe pipe 123 into'the top of'the tank 10, the, valve 45* having been turned to communicate with said pipe 123. p 4 a The tank having been filled, the inlet valve 121 is closed and the valve 56 opened and the valve 45* is then turned so that the liquid may flow from said tank through the strainer" 43 into the pipe 12 to the pump from which it is forced through the pipe 45 to and through the valve 49 into the pipes 50-51 to the valves 84 .which if open will permit the of the tank 10. In the heater chamber 113 discharge of the liquid through the oil spray pipes 73. These. pipes '7 3 may be moved latmovement being about the axes of the depending lpipes 69 and said pipes 73 having a erally of-the frame 13 by the handle 82, said 5'; the end of a pipe 101, the op osite end of movement also about the axes of the p1 es 72 so that-the pipes 73 are always perpen icular to the axis of the frame 13' 1nto whatever position they may be moved. I When the oil spray system is ifiuse'the valve 65 is closedbut 1f it is desired to empty the tank this valve 65 is opened and the valves 84 and 122 closed, the valve a5? being turned to communicate. with thepipe 64. The liquid will then be discharged through the pipe 64. The end'of this ipe isthreaded and' a hose may be attac ed [thereto so i that if the tank is filled with water a stream may be forced therethrough for the purpose of putting out fires. Wh1le the ump 30 is in operation, if any of the cuto valves are closed temporarily the liquid dischargefrom i the, pump 30 will pass through the bypass pipe 46 to the inlet side oi the pump,-the relief .valve 47 permitting this operation when a predetermined pressure has been reached. When heavy oils are used that require heat to put them in suitable condition for use, the heater 114 is lighted and as the heat therefrom passes through the pipes 112 into the chamber 110, the oil is circulated through the tank. .This is accomplished by turning Y entire length/of the hot air pipes 112 and pass through the pipes 54, 48, and 42 to the inlet side of the pump. -A constant circulation'of the oil is thus created, which is con tinued until the oilis of the proper consistency,= and has a predetermined and uniform This circulation temperature throughout. may be created either while the vehicle is moving or at rest. This is of considerable importance] for it is essential that means should be provided whereby oils of diiferent kinds ma be difierently treated and that they be 0 uniform temperature and consist enc'y. The valve 122 is operated by means of th lever 124 connected to the valve stem by a link 125 as shown in Fig. 8.

On each side of the tank 10 is a reseryoir 126 adapted to contain kerosene or some similar oil. From each reservoir 126 extends a pipe 127 having a valve 128 there in and the two pipes 127 both connect with the pipe 129 extending to the rear end of the tank where it connects with'a transverse pipe 130 the ends of which connect with by; a handle 141. By

the heaters 114114.

The' flow of the oil to. the heaters 114114 is regulated by thevalves 1,31. The discharge end 132 of each heater is provided with a head 133 having a discharge orifice 134 immediatelyin the rear of a bafile plate 135 secured to the supports 136 extendmg forwardly from the brackets 115.

A closing plug 137 is threaded to the end of the head 133, said plug having a radial slot 138- in its inner endthrough which any accumulated deposit may be driven out by the flame when the plug 137 has been unscrewed sufliciently to uncover the outer end of said slot 138'. This is of considerable importance and should be done once each day and then the plug 137 \sh0uld be again screwed into the Fig. 6 of the drawings.

Each of the reservoirs 126 is connected by pipes: 139 to an air pump 140 operated means .of thispump 140 the oil in the reservoirs 126 is maintained at a pressure of 40 lbs."

The amount of oil assing to the heaters 114 may be regulate by the needle valves 131 which are always closed before commencing, to spray. 'These valves 131 should be kept closed until the fire tubes 112 are wholly covered with material in the tank 10 and-may then be opened and the burners 134 of the heaters. lighted.

the pump 30 is .run until the position shown in The tank 10 may either be filled by pump suction as hereinbefore described, or it may be filled by any suitable gravity supply by removihg the manhole cover 140 and fi' ling through the opening by any suitable conducting hose or pipe.

When using heated material in the tank 10 it is im ortant that the tank should not be quite full as some space must be allowed for expansion.

When the tank 10 has been filled bymeans of the pump 80 the'latter is stoppedand the valve 121 is closed.

When circulating the material in the tank 10 the valve 56 should be wide open and the pump 30- started at a moderate speed. The pum is'ke t runnin the material is t orough y agitate to a until proper tem e'ratnre asshown by a thermometer provi ed for this purpose. The loea-" tion of the delivery end of the pipe 123 at the bottom of the-forward end of the; ta ii is of eat importance as by this means the oil passing. through the pipe 122 along the upper side of the tank is gradually heated and when discharged into the bott' mof the tank it will flow toward the rear end of the tank in contact with the hot air tubes and then rise above the tubes and flow toward v the front end of the tank. A constant circulation of the material is thus maintained until the temperature of all the material is uniform.

The burners are then extin ished and the valves '45" opened, permitting the material to be forced by the pump 30 through theoil spray pipes 73.

Whenever it is necessary to stop the. distribution of the oil'for any length of time before the tank is entirely emptied, the valve 56 is closed and the vent cook 62 is opened. The valves-84 are then'opened and piping system is entirely free from material. The circulating valve 122 is then closed and the kerosene oil valve 142 is opened,

allowing a jet of kerosene oil toenter the I pump and piping system,

and the pump 30. is kept running until the kerosene oil forced. through the "piping system has thoroughly. cleared the same. I v The drain cocks 67 are then opened to permit the draining of the strainercasings 43 and 44.- A pipe 143 leads from the top of the tank 10 with its discharge-endat 144 beneath the tank. This provides a means whereby any excessive amount, of material in the tankwi-ll be discharged upon the road over WhicH the truck is traveling, and will prevent any of this material being scattered over the outside of the tank or on the operating parts.

When it is desired to spray-by means of a hose, thehose may be attached to. the uni used when desired by means of the plate.

148, hinged at its upper edge as indicated at 149 and adapted to be supported in open position by means of the chain 150.

When the material in the tank 10 is heavy oil and it is being heated, the plate 148 is held open by the chain 150.

During the operation of heating heavy oil the valve 45* is turned so as to direct the material into the pipe 123 and cutit oil entirely from the pipe system, thus 'prevent-- ing the pipes from becoming clogged with forkee 4 p I materia in the" tank, the various port ons said material, which obviously willhar dcn as soon as it'becomes cold.

This'is; of considerable importance as it is necessary to keep the pipes clear. and only perlnit'the heavy oils to pass through when theylhave the'proper consistency and temperature and under pressure created by the pum 80. I

. en the pump 30 is not in operation, the valve 45 ma pi cs 48 and 123. en the valve 45" is turned to direct the material into the pipe 123 and the valve 122 is closed, the valve maybe opened and the material discharged through the ipe 64.

The valve 122 may be used to regu ate the pressure of; the material passin through the pipe system, it being obvious t at if said valveis partly open, a portion of the material will pass through thevalve 122 and pipe 128 into the tank, and "if closed the material passing. through the pipe system will be underthe pressure created by said pump acciirdingtothe setting-of the relief valve 47 'One of the reservoirs 126 must be .filled' with kerosene oil or some equivalent which may, used in the heaters 114, but in some case'sgwhere certain kinds of material are ,b'e ingusedfin the tank 10, kerosene oil is not a suitable flux, and in this case the other reservoir 126 ma be filled with some other flux which may e used when the pipe s'ys tem is to be cleared.

Among 0131184 advanta es of the present invention it will be note thatthe material is heated by means ofa dry heat, passing through the hot air pipes 112 and that during the heatingprocess means isjprovidcd mg up a constant circulation of the thereof coming. successively into contact e turned also into pusi tion to cut 0 the'material from both the sure was used.

with the pipes 112 until the entire contents of the tank 10 have a uniform temperature.

In view of this constant circulation of the material there is no danger of burning the material.

rial as would hethe'case if steam heat were used and it is ObVlOllS that heat of any required temperature --is available at once regardless of weather conditions. ,7

With this device there are no delays as the material may be heated while the truck is on the way to the place where the spray-. ing is to be done.

Any volume or temperature of material may be evenly and uniformly distributed by the apparatus and said. apparatus is adapted for use in distributing either cold or hot material.

Means are provided whereby the entire pipe system may be thoroughly cleared of l and the tank may be filled with water and the apparatus then used for watering the streets.

It is also possible by disconnecting the chain 27 and disconnecting the securing .bolts 146 to remove the demountahle frame 13 with its tanknnd piping system from the chassis. 15 and then use the truck for any There is at no t me any internal pressuifi within the tank, thereby making it possible to usea thinner shell than would be the case in tanks in which steam or other pre s- All the pressure required is obtained by means, of the rotary pump 30 which may also beused for loading.
